SEPARABLE FASTENER I Filed Dec. 26, 1935 INVENTOR J1me filler; flobrolu ATTORNEY Patented Nov. 15, 1938 UNITED STATES PATENT "OFFICE 1 Claim.

This invention relates to new and useful improvements in a double tie sheet for beds.

The invention has for an object the construction of a device as mentioned which is adapted to be used in combination with a bed having longitudinal side horizontal bars beneath the mattress thereof, and vertical side bars at the sides thereof.

' More particularly, the double tie sheet according to this invention is characterized by a bottom sheet of the width of the mattress of said bed and having cords or the like at the sides adapted to be attached to said horizontal bars, and a top sheet of the width of said mattress and having cords or the like at the sides, and the cords at the rear portion thereof being adapted to be attached on said side horizontal bars and the cords at the front portion thereof being adapted to be slidably connected with said vertical bars.

A further object of the invention is the arrangement of the front cords upon the edges of the top sheet so that they may be removed and replaced in different positions.

A feature of the constructions described in the previous paragraphs is that the possibility of a baby being strangled by the sheets is entirely eliminated since the top sheet is yieldable in that the front strings thereof may slide on the bars.

A further object of the invention is a construction whereby the front portion of the top sheet cannot be tied down to the horizontal bars so as to make the device fool proof.

Another object is the construction of a device as mentioned which is simple and durable and which may be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claim in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure- Fig. 1 is a perspective view of a bed to which a double tie sheet, according to this invention, may be applied.

Fig. 2 is a fragmentary transverse sectional view of the bed shown in Fig. 1 witha mattress and a double tie sheet according to this invention thereon.

Fig, 3 is a side elevational view of a mattress with the bottom sheet according to this invention engaged thereon.

(c1. u ease) Fig. 4 is a perspective View of the bottom sheet per se.

Fig. 5 is a longitudinal sectional view of a mattress with the double sheet engaged thereon.

Fig. 6 is a perspective view of the top sheet.

Fig. 7 is a fragmentary perspective View similar to a portion of Fig. 6 but showing a modification.

Fig. 8 is a sectional view taken on the line 88 of Fig. 7.

The double tie sheet, according to this invention, comprises a bottom sheet II) of a width substantially corresponding with the width of a mattress II to which the sheet is to be engaged. This bottom sheet I0 is provided with cords II at the sides thereof at the front and rear portions. These cords are adapted to be attached upon horizontal bars I2 of a bed to which the device is applied. In conjunction with the bottom sheet I0 there is a top sheet I3 also of the width of the mattress, which has cords I4 or the like at the sides at the rear portion thereof and which has other cords I4 also at the sides but at the front portion thereof.

The rear cords I4 are adapted to be tied to the horizontal bars I2 of the bed so as to hold the sheet in position. The front cords I4 are adapted to be slidably tied to the vertical bars I5 of the bed.

This invention is intended only to be used in combination with beds having horizontal bars for supporting the spring and mattress for the bed, such as the bars I2, and also having vertical slide bars such as the bars I5.

The bottom sheet I0 is adapted to have its end portions I0 and Ill tucked under the front and rear ends of the mattress. The rear portion I3 of the top sheet I3 is adapted to be tucked under the rear end of the mattress, while the front end I3 is adapted to be bent rearwards a short distance so as to be at a convenient height for a child sleeping in the bed.

The front cords I4 are rel-easably laced through button holes I6 formed along the sides of the sheet I3. When desired, the cords may be removed from certain of the button holes and engaged in others of the button holes.

In Figs. '7 and 8 a modification of the invention is disclosed in which the top sheet I3 has rigid inserts I8 mounted on the ends thereof. These inserts may be of composition rubber or other stiff material. Each of these inserts is formed with an opening I9 having a reduced mouth I9 Cords or the like I I" are secured together at their inner ends and are connected with buttons 2| which are adapted to engage beneath the inserts l8. Each button 2| is of a larger diameter than the opening [9 so that as long as the cords H" are drawn upwards, the parts remain connected. Should the cords ll" be moved relatively downwards they may pass between the restricted area l9 and so disconnect from the insert.

Bushings 20 are slidably mounted upon the vertical bars l and are adapted to frictionally maintain adjusted positions. Preferably, these bushings should be of rubber. The cords [4" are adapted to be tied upon the bars l5 above the bushings so that they are restrained from. slipping downwards. The bushings 20 must be at a suflicient height so that the front portion of the top sheet l3 may be raised as is required when a child sleeps beneath it, but at the same time, to prevent the disengagement from the cords I4" through the'mouths I9. If the child sits up there is a relative movement between the front portion of the sheet l3 and the cords [4". Should these cords slide upwards there will be no disconnection, but should the cords maintain their positions, the cords will disengage from the inserts of the sheet.

The feature of the invention resides in the fact that the sheets are held in position. They will not slip upwards or downwards as is customary with standard sheets, especially if they are of insuflicient size so that the edges and ends thereof may not be properly tucked under the mattress. While the sheets are tied down the front portion of the top sheet is loose or may be freed so as to prevent any strangulation of the baby.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claim.

Having thus described by invention, what I claim as new and desire to secure by United States Letters Patent is:

A separable fastener of the type described, comprising a stiff sheet-like member having a narrow opening in one edge thereof merging into an opening of increased size inwardly thereof forming shoulders, and a button-like member having one or more flat bendable securing-tapes attached at one of their ends to one face of said button-like member, said edge opening being only of a width sufficient to receive said tapes edgewise, said tapes being within said larger opening, said button having its said face abutting the material of said member around said larger opening to prevent said tapes from being pulled axially from said larger opening and said tapes having their edges abutting said shoulders to prevent said tapes from being pulled through said narrow opening in their crosswise position except when an excess pull is applied thereto.
